System requires the user classification management, system distribution structure, resource sharing, etc., should give full consideration in the design of advanced systems, security and usability, more than 400 concurrent users to meet the same requirements for use.
1, the user classification management
System should be in accordance with the Council, county and city public security bureau, the primary branches are forces and police stations at least three levels of units of the user and the computer user terminals at different levels. Urban management terminal which can monitor or manage the city's users, other levels of management terminal to manage the local user's permissions, can be held independently of local video conference, video conference held in the Council forward and simultaneously transmitting the sub-site images, while to the local video image of the meeting.
2, the system distributed architecture
According to Metro Police Taizhou tree characteristics and requirements of the system with distributed architecture, the server implementation of the cascade model, in principle, the Council equipped with 2 video server key management Urban organs, Development Zone Branch, Jiaojiang Branch, Huangyan Branch, Bridge Branch, Wenling, Yuhuan, the user terminal; in Linhai City Public Security Bureau configure a video server key management station waterfront, 3, roof, Xianju of user terminals; Police School configure a station video server (already purchased ) key management school of distance education video input and the whole network of distance education applications to meet the whole network in nearly 400 cases, the number of concurrent users, ensuring the system image quality 640X480, 25 帧 over to normal operation.
Intelligent routing system should have the server capabilities concurrent users in a server exceeds the required standards, the other free streaming video server can automatically part of the user; systems in the case of a server failure, other servers can automatically replace management, in order to ensure system reliability .
System should support multiple conference rooms and multi-server proceedings.
3, the system utilization and sharing of existing resources

5, the system scalable
Taking into account the application of the system, including the city of more than 200 grass-roots public security, more than 3,000 computer user terminals, networked video conferencing, distance learning networks, Internet video telephony and other functions, the building began to be considered compatible with the existing system and scalability of existing systems, increase in the number of concurrent users in the case, only by increasing the video server, you can increase the concurrent users.
Application:
In actual use, the network video conferencing, distance learning, video surveillance, video telephony and video live to achieve five functions, improve the Alarm Taizhou Public Security Bureau to improve the efficiency and the speed of police response, enhanced police training, and reduce the time and The cost really makes the original single way of working become more fit in with the national security sector personnel and the optimization of hardware and software configuration update, the "police training and technology," fell to reality.
